    摘要: Disclosed are an artificial dura and its manufacturing method. The artificial dura mater consists of an electrospun layer by electrospinning. The electrospun layer has at least a hydrophobic electrospun layer. And there is at least a hydrophilic electrospun layer on the hydrophobic electrospun layer. A transition layer is formed between the hydrophobic electrospun layer and the hydrophilic electrospun layer. Cytokine and/or medicine can be added with every layer of the artificial dura mater, furthermore, can be adhered to the hydrophobic electrospun layer and/or the hydrophilic electrospun layer by bio-printing technique. The dura mater has a characteristic of good biocompatibility, accelerating the regeneration process of its tissue, excellent repairing effect, anti-adhesion, complete absorption, good mechanical properties, low infection rate, and capability of adding other therapeutic substances.

    摘要: In a process for producing tubular shaped fibrous articles of small diameter by heating and cooling a fibrous bundle containing at least 20 weight % of hot-melt-adhesive composite fibers, the improvements comprise using a shaping apparatus including an injecting chamber (1), an injecting hole (2) formed in the wall of the chamber, a fibrous bundle outlet (5) provided with a nozzle of a desired shape in cross-section, a cylindrical pipe (6) for introducing the fibrous bundle, which has a cross-sectional area larger than that of said outlet, is located at a position opposite to the outlet and projects toward the outlet and terminates in the injecting chamber, and a core pipe (7) which is open at its base on the outside of the injecting chamber, has its one end inserted through the cylindrical pipe and extending into the nozzle through the injecting chamber, and having a vent (8) in its portion exposed within the injecting chamber, and passing the fibrous bundle through the cylindrical pipe to the outlet, while injecting a hot compressed gas through the injecting hole, thereby to heat and shape the fibrous bundle to and at its hot-melt-adhesive temperature.
